This invention' relates 'to aznovel and im-` proved car truc-lr pedestall `andl Vmoreparti cu-` larl to a novel and imnroved hner for the withthe journal box with'whieh it ooperates.

'Brieflyy my. invention comprises a liner made preferably'v of rhigh carbon steel and arranged to be sprung into position on-the inner face of each jaw of a pedestal, where it is retained by its inherent resiliency.

in any event the liner may be easily removed and replaced as it becomes worn.

ln the ac compan'yingv drawing in which l have sh wn a selected embodiment of my invention 1` Fig. l is an elevation of a truer-hav ingmyinvention'embodied therein. N Y Fig. 2 is an enlarged elevation of a pedestfil to which-my improved liners are at tached.
